岩矿鉴定技术在商洛市商州区桐树沟金矿中的应用

Application of Rock and Mineral Identification Technology in Tongshugou Gold Mine,Shangzhou District,Shangluo City

桐树沟金矿为商州-丹凤深大断裂北侧附近的1处中型金矿床,矿体受断裂构造控制明显。在找矿过程中,岩矿鉴定技术在矿物定名、矿化蚀变期次划分、矿床成因研究等方面发挥非常重要的作用。本文以桐树沟金矿为例,研究矿区地质特征和蚀变特征,划分成矿阶段,分析矿体特征、矿石特征和找矿标志,从而明确矿床成因。研究表明,桐树沟金矿是与秦岭造山活动相关的中低温热液型金矿床。

Tongshugou Gold Mine is a medium-sized gold deposit located near the north side of the Shangzhou-Danfeng deep fault,and the ore body is clearly controlled by the fault structure.In the process of ore exploration,rock and mineral identification technology plays a very important role in mineral naming,mineralization and alteration stage division,and deposit genesis research.Taking Tongshugou Gold Mine as an example,this paper studies the geological and alteration characteristics of the mining area,divides the mineralization stages,analyzes the ore body characteristics,ore characteristics,and prospecting indicators,in order to clarify the deposit genesis.Research has shown that Tongshugou Gold Mine is a medium-low temperature hydrothermal type gold deposit related to the Qinling orogenic activity.
